Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain. ACS cannot be held responsible for errors or consequences arising from the use of information contained in these “Just Accepted” manuscripts.

(a) L-SWNT pastes 1 year after preparation. (b) MWNT suspension after 1 year (left) and S-SWNT suspension after 10 days. (c) Laser microscope images (left) and optical microscope images (right) of blade-coated CNT films.
(a) The volume-based size distributions of CNT agglomerates in L-SWNT paste (black) and MWNT suspension (white) obtained by a particle image analyzer. ISO area diameters were measured as agglomerate sizes. Insets are SEM images of LSWNT (right) and MWNT (left) agglomerate dropped and dried on SiO2/Si substrate. (b) High-resolution SEM images of L-SWNT (left) and MWNT (right) films showing the CNT network structures.
